The Founder
“Stories that entertain, illuminate, and leave people with something worth carrying home.”
Sandra Gronberg
Sandra Gronberg founded Letterbox Films with a calling to create original, cinematic stories that entertain, illuminate, and leave people with something worth watching.
Founder Sandra Gronberg has always believed that stories have the power to move us, surprise us, and remind us of what matters. Her Christian faith is at the heart of how she sees the world, inspiring stories rooted in hope, redemption, and the belief that even in the darkest moments, there is always room for light.
Based in The Woodlands, Texas, Letterbox Films Inc. is a woman founded, independent production company. Developing original, character driven films and series. Sandra created the company to tell meaningful, entertaining stories, build compelling roles and create productions where actors and crew are valued.
Today, Sandra leads a growing slate of features and series built on that belief, working alongside writers, filmmakers, and partners who share her vision for cinema that moves people. Every project begins with the same question she asked at the very start:
Will this story be worth opening?
